Quantitative Aptitude Trains Study Material
This chapter is basically an extension of.the ‘Time and Distance” chapter discussed earlier, therefore, we will use here the basic concepts like Speed, Relative Speed already discussed in the earlier chapter. Here, the focus will be exclusively on problems related to trains. The variables involved are again the same—Time, Distance and Speed. •Assumptions : For all purposes, unless otherwise specifically mentioned, we will assume that the speed at which the train(s) covers the distance or performs the journey remains constant over the journey which we call the average speed. The size of the person, telegraph post, pole etc. is negligible in comparison to the length of the train or the platform.
